How to select default codec?

[cshong]

SMPlayer version: 0.6.9 (SVN r3447) (installed through Ubuntu Software Center)

I want smplayer to use rv3040 (drvc.so) as default codec for all .rmvb files, so that smplayer will use rv3040 each time when I watch a .rmvb file. How can I do this?

Problem:
For each different .rmvb file, I have to manually select rv3040 codec by going to Options -> View info and properties -> Video codec, then select rv3040. Let me explain in more detail. When I watch a .rmvb video file, I select rv3040 as the codec, SMplayer will remember this setting for that file. Next time when I watch the same file again, SMplayer will use rv3040 codec again. But, when I watch a different .rmvb file, SMplayer will use back the ffrv40 codec, and I have to set it to use rv3040 codec again.

So, how can I set rv3040 as default codec for all .rmvb files, so that I no need to manually select rv3040 codec for each different .rmvb file?

I think you could try to pass to mplayer (preferences -> advanced) the option -vc rv3040, (with the comma at the end). This way it will try to use the codec rv3040 first, then the others.
